The aim with this paper is to study Karl Popper?s view on realism and relativism. Further aim is to see whether those ideas have been consistent over the years. The paper argues that Popper since his first interest in philosophy has taken a realistic and antirelativistic attitude. Only his arguments for this position have been developed to meet his critics.Common sense speaks for realism but can neither be proven nor refuted.

In this study we examine how much latency is required in an RTS-game (Real-Time Strategy) before the player quits the game. In the study latency is simulated in the games Age of Mythology and Starcraft: Brood War with the program WANem, and then the testplayers are asked ?Do you want to quit because of latency??. This data is then gathered and compiled into graphs to show the results. These results show that the limit for when players want to quit differs between the two games and that there are two factors that play into this.

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

As trucks are getting more and more advanced, information about their weight has become a key factor for controlling them in a more fuel efficient and safe manner. Knowing the mass of a heavy duty vehicle in real time has been a difficult challenge for the truck manufacturers. With the processing power for electronic control units in trucks steadily increasing, more advanced algorithms for calculating the mass has been developed, but at the moment there still is a wish for better performance.Since there is a lack of good information regarding the external forces acting on the vehicle, forces that depends on the slope of the road, foundation of the road and the wind, the methods have to be able to disregard these. Such an approach, based on an indirect least square solution, has been evaluated in this thesis. The results have been promising and based on these a recommendation about further evaluation has been made..

This essay is questioning if the state as an unsecured creditor in a bankruptcy proceeding, according to the principle of equal treatment, has the same rights as the other unsecured creditors. The principle of equal treatment means that creditors with unsecured claims are supposed to have mutually equal rights to dividends in a bankruptcy. In the Swedish bankruptcy law from 1987 there are recycling rules which means that some legal actions taken by the bankrupt debtor before the bankruptcy can be recycled to the bankruptcy estate. These rules do not apply on taxes. This essay analyzes whether the state should have this advantage or not.

Bakgrund och problem: År 1999 blev det tillåtet för idrottsföreningar med elitverksamhet att bilda aktiebolag. I dag har endast 23 stycken idrottsföreningar av ungefär 20 000 valt att bilda aktiebolag som man upplåtit sin serieplats till. Inför Riksidrottsmötet 1997 lämnade AIK, Svenska ishockeyförbundet samt några enstaka mindre föreningar in en motion om att idrottsföreningar skulle få möjlighet att driva föreningen i en alternativ assoicationsform. Argumentet för denna motion var att detta skulle ge en möjlighet för svensk idrott att kunna konkurrera sig med internationella föreningar. En bättre ekonomi skulle ge bättre sportsliga resultat.

As the cities are becoming more crowded, the urban distribution has become a major logistical challenge. Some commonproblems in the inner cities arelimited accessibility and idling. Many of Sweden's municipalities are above the limit values for PM10limit set by the EU.Sundsvall is one of these municipalities and has the vision to create a sustainable city and region. Sundsvall LogistikparkAB is part of an EU project, SMARTSET, which is collaborationbetween several cities in Europe. SMARTSETSundsvall is about to develop a market-based sustainable model for city logistics.

This essay describes some factors that may effect small business survival in relation to becoming a supplier for bigger companies that may implement the use of EDI for electronic invoicing.The purpose of this study is to analyse and evaluate what impact may occur during the introduction of EDI between small and big business.Following on from the introduction of methods used in this study there will be a complete analysis made detailing results.From our research we have found that most small business have developed a professional working relationship between themselves and their clients.The adoption of EDI by big business has revolutionised the day to day dealings between both supplier and consumer in that EDI has empowered both chains to collaborate data in real time.In conclusion our research illustrates that in order for small business to survive the must implement EDI. The results of our study have shown that the introduction of EDI to both small and big business has had a positive outcome..

Allt större och större andel företag väljer att presentera och förmedla varor och tjänster via e-handel. En viktig aspekt vid e-handel är att kunden känner förtroende för e-handelsapplikationen och företaget. Denna rapport redogör för vilken inverkan multimediala inslag har för förtroendet av en e-handelsapplikation, vid initialt användande. En undersökning har genomförts med hjälp av en kooperativ utvärdering av fyra e-handelsapplikationer vilka innehåller olika typer av multimediala inslag har.Resultatet av undersökningen visar att multimediala inslag inverkar positivt på förtroendet för e-handelsapplikationer. Däremot finns indikationer på att för hög grad av multimedialt inslag inverkar negativt på förtroendet för e-handelsapplikationer..

I dagens samhälle blir det allt vanligare att umgås genom datorn. Chatter, bloggar, forum och spelsajter växer lavinartat. Hur stor är utbredningen av detta bland skolungdomar och påverkar det det vanliga kamratumgänget IRL (In Real Life)? Hur ser lärare på chatt? Kan man dra nytta av det i undervisningen? Dessa frågor, bland annat, har tagits upp i detta arbete för att försöka koppla skolan till ett växande chattintresse..

A vulnerable group in society is people with ASD (autism spectrum disorders) or autism. This group seems to increase, mainly due to genetic factors but also environmental problems. Medical research has accelerated in the U.S. and Europe. The biggest problem for people with disabilities is the inability to communicate, both verbally and socially.

Thick skin in Texas - an investigation on storytelling and pictorial language. I took my starting point in a story about the cowboy Jaquin, who goes to the Tivoli, where he gets caught up in a dramatic adventure. I extracted three scenes from this story, and I experimented with whether it was possible to make the separate scenes tell their own story, in three separate drawings. Without depending on the frame story or on any kind of text. In this project I partly wanted to explore the possibilities of the drawing.

Close to the city center of Reykjavik lies the combined national- and university library of Iceland. Usually, these two types of institutions are separated. The purpose of this essay is to investigate how the library in fact selects the new digital material to offer the users in Iceland, and if the combined mission creates any problems or conflicts.The investigation examines the planning and the content of the digital library, what user groups are addressed and how the organisation is held together despite the different missions. If cultural context in Iceland makes a difference for what is selected and offered to the users is also discussed.Six informants in strategic library positions dealing with the digital national- or university library, were interviewed. The answers have been analysed in light of the library&information literature on building and maintaining digital library collections and organizational and marketing theory.The main result of the study is that the informants do not see a conflict between the missions of the organisation, although traces of a struggle were found in some areas.

In industry applications, such as power supply plants, the issue of interaction between fluid and structure is always presented. More precisely, the fluid flow affects the structure by applying force(s) on it and vice versa. As a result, the structure can move (vibrate) or deform. A good understanding of this problem can help to design the system in term of safety, stability and efficiency.This project aims to optimize and test the Unicorn FSI solver from the FEniCS project [1] to simulate the interaction of fluid and structure in an experiment, which was carried out at Vattenfall Research and Development. The target is to improve the Unicorn FSI solver to cope with a real industrial problem.
